摘要: 为探讨浙江不同品种(系)香榧叶片和种实品质的差异,以同一生长环境和立地条件下的12个品种(系)香榧植株为研究对象,测定叶片表型、种实外观和营养品质等生理指标,对数据进行相关性分析和主成分分析,同时建立12个品种(系)香榧种实的品质评价模型。结果显示:12个香榧品种(系)的叶片长度介于15.239~21.322 mm,磐安长榧的叶片最长;叶片宽度介于2.691~3.775 mm,长籽象牙榧的叶片最细;12个香榧品种(系)的出仁率为45.737%~79.481%,最高的是象牙榧;油脂含量为40.702%~54.284%,最高的是早缘榧;可溶性蛋白含量为15.321~32.079 mg·g-1,最高的是龙凤细榧;不饱和脂肪酸含量为83.384%~90.540%,最高的是东榧1号;亚油酸含量为41.394%~48.170%,最高的是东榧2号;金松酸含量为7.850%~12.963%,最高的是安圆榧。经主成分分析后提取出5个主成分因子,建立香榧种实品质评价模型,综合所有指标的种实品质排名为:早缘榧>龙凤细榧>安圆榧>东榧2号>立勤细榧>象牙榧>东榧1号>小籽象牙榧>磐安长榧>圆酥榧>长籽象牙榧>东白珠。研究结果可为选育稳定高产的香榧新品种奠定基础,进而更好地保护和利用香榧种质资源。

Abstract:

To explore the differences in leaf and seed quality among different varieties (strains) of Torreya grandis in Zhejiang, this study focused on 12 different varieties (strains) of T. grandi grown under the same environment and site conditions. Physiological indicators such as leaf phenotype, seed and fruit appearance, and nutritional quality were measured. Correlation analysis and principal component analysis were conducted on the data, and a quality evaluation model for the seeds of these 12 varieties (strains) was established. The results showed that the leaf length of the 12 T. grandis varieties (strains) ranged from 15.239 mm to 21.322 mm, with Pan’an Changfei having the longest leaves; leaf width ranged from 2.691 mm to 3.775 mm, with Changzi Xiangya having the narrowest leaves. The kernel yield varied from 45.737% to 79.481%, with Xiangya having the highest yield; oil content ranged from 40.702% to 54.284%, with Zaoyuan having the highest oil content. Soluble protein content ranged from 15.321 mg·g-1 to 32.079 mg·g-1, with Longfeng Xifei having the highest content; unsaturated fatty acid content ranged from 83.384% to 90.540%, with Dongfei No.1 having the highest content; linoleic acid content ranged from 41.394% to 48.170%, with Dongfei No.2 having the highest content; and junceic acid content ranged from 7.850% to 12.963%, with Anyuan having the highest content. After principal component analysis, five principal component factors were extracted, and a quality evaluation model for T. grandis seeds was established. Based on all indicators, the ranking among varieties (strains) was: Zaoyuan>Longfeng Xifei>Anyuan>Dongfei No.2>Liqin Xifei>Xiangya>Dongfei No.1>Xiaozi Xiangya>Pan’an Changfei>Yuansu>Changzi Xiangya>Dongbaizhu. The research results can lay the foundation for the selection and breeding of stable and high-yielding new varieties of T. grandis, thereby better protecting and utilizing the germplasm resources of T. grandis.
